There was a set in which A1, A2 and A4 were given. And the equation A(n-1)xA(n+1)=An^2 (+/-) 1.

We had to find A7. Don't remember the answer, though. Was there a second question in this set?

amitnsitian Says

no you can very well multiply 0 and 0. 0 is a square of an integer without an iota of doubt

Yeah totally agree with you. 0 is also an answer to be considered.

Btw, Don't u guys think its a relief that they took back the test paper. I cant even imagine dissecting that paper. TIME cutoffs are quite low? Do you think it would be the same? looks like their CAT cutoffs were a little below the actual ones.

Btw, is this the usual practice, am writing XAT for the first time. Did they take back the test paper last year too?

a+b+c+d+e=10
a+b,b+c,c+d,d+e X is the maximum of dese.
Find the mininum value of X..my take would be ans is 4.ie when a=b=c=d=e=2.

Was it mentioned that ab,c,d,e are positive integers or just integer?

friends
i remeber only 3 question.
a fuction was fiven whr f(0)not equal to 0,f(1)=3 and find values of F(3)and F(7 )
1.f(3)=18
2.f(7)=843
3.value of n for,n/(20-n)
here n=18,16,10.
these are only 3 values which n can take as 1 ,4 and 9 are only perfect square.

yes 0 is an integer

According to me, answer to that slope question is 2/3 - option (a)

for that, a +b+c+d+e=10 wala question i marked

hey both our answers match but isnt the answer of second question as given above be 3.5i doubt it was real nos..i think it was integers

A, B, C, D, E, F, G are seven integers; arrange them in increasing order.

First four numbers are in AP
Last four numbers are in GP
E is highest = 960
There are no numbers between A and B.
There is exactly one number between E and G.
D is the lowest.

Related Questions:

What is the value of D?

What is the common difference?

What is the ratio E/A=?

What is the postion n value of A?

Anybody solved this? Did I forget any condition here?

a/d=c/f==something/someting=>1..not sure about the exact numerals

ya!! right 0 is an integer
but remember always 0*0 ( vis-a-vis 0^2) is undefined..u cant call it a square of an integer!!!

correct me if iam wrong!!!!

Yes, zero is an integer. You should exclude zero only if the question says "Natural Number" or "Positive Integer". But since the question was just "integer" zero will need to be included.

Initially I too thought that it was one, but then the answer is actually 2.

I think we had to remove 3 road segments to completely cut of link btwn B and D...
Can anybody confirm...
I drew it on te paper and thought i was pretty sure while marking 3 :huh:

Answer to the hyperbola problem was 9x^2 - 16y^2 = 144.
Jnr. Prof. probability was 5/6
Money prob. answer was 10563 (I think 2nd or 3rd option)
The triangle problem in which angle A was 60 degrees, the bisector of that angle divided the opp. side in the ratio 1:2, to find --> AMC. whr M is the point at which the angle bisector met the opp side. The answer was 120. The triangle ABC, will work out to be a 30 60 90 rt triangle and rest will follow frm the angle bisector theorem.

three more quants questions whic i could recall are..

2. A network of roads connecting each other..ABCDEFGH were the points..
minimum how many roads shud be removed to stop all traffic b/w B and D.
My ans 1.only road R2 had to removed (tho not very sure).

Initially I too thought that it was one, but then the answer is actually 2.

but tell me is 0 an integer??

continued
(10)f(n)=n/20-n answer will be only for n=16 f(n) will be square of a natural number

As far as I remember, the question was, for how many values of n n/20-n is a square of an integer.
So for n = 0, 10, 16, 18, f(n) will be 0, 1, 4, 9 resp. ie. 0^2, 1^2, 2^2, 3^2.
Thanks,
Bill...

three more quants questions whic i could recall are..

1.three points A(0,0),B(0,9) and C(6,0) lie on the co-ordinate axes.
Points R and S on AB such tht AR=RS=SB,points P and Q on AC such tht
AP=PQ=QS.RC intersects PB at point X,find slope of line AX.
My ans 3/2.

2. A network of roads connecting each other..ABCDEFGH were the points..
minimum how many roads shud be removed to stop all traffic b/w B and D.
My ans 1.only road R2 had to removed (tho not very sure).

3.A DS question was a LR type.5 or six ppl sit in a row.One person between D and E and two between B and C(i think).
my ans. only statement which said B and E are next to each other was sufficient to determine the person sitting at the 1st seat..in this case D.again not sure..plz reply n give in ur solutions..

for f(n) = n/(20-n) . .. . . this also holds true for n = 10... f(n) = 1 which is the square of an integer....

so in all 2 values..

though i got it wrong :((

Guys....a+b+c+d+e = 10..it was +ve real numbers.......so answer was 3.5 with the combination 3+0.5+3+0.5+3 = 10......... so range is

It was asked maximum value of the sum of numbers taken two at a time, so in the above case answer is 3+3 = 6, hence answer is >4 hence the interval should be .. I hope that I am clear..

Cheers,
DMA Controller.

continued
(9) x+p=y , 2x+2y= p like that p=0
(10)f(n)=n/20-n answer will be only for n=16 f(n) will be square of a natural number
(11) f(x)= x/10 quotient if divisible by 10 otherwise x+1 answer is 9

guys its not its see my earlier post for explanation

so correct answer upto now
(1) p+q =7
(2)25
(3) average =8
(4)
(5) one data sufficiency question of triangle right angle ---- can't be calculated
(6) table 1 st anwer decreasing order start from petrochemical option 1 in set A ( export and import)
(7) second question of same table petrochemical again
( one value close to 40 but will be slightly less 39.-- correct answer
so , come one mba wannabies increase the count

DMA Controller Says

I agree with you, the answer is 4. The only problem was that among the options there were 2 options which included 4 i.e and . I think answer would be since the answer has to be greater than 4. Quant gods please confirm

Guys....a+b+c+d+e = 10..it was +ve real numbers.......so answer was 3.5 with the combination 3+0.5+3+0.5+3 = 10......... so range is ....

and for the number substitution 10563...depending on that u can get the three.....and average on row and column 8...

(writing on behalf).........that missing average is 8 as option were 6,7,8,9,12 if average assumed 12 then column sum is 36 but 1 column value was 1 so sum of other two element should be 35 as highest no. available was 13 it is not possible for 9 column sum is 27 again sum to be 26 highest 13 ( only one 13 ) so not possible .,,,,
there was one column value 15 so if 6 is average column sum is 18 but value available were 2,3 ,..... so minimum 3 cant be made so it can't be 6 ...
for 7 it is 21 but 20 sum will not form without contradiction
so answer was 8

There was one question in which letters substituted for numbers and there was addition of 3 nos...

1.Which no from 0-9 is not used ?
Ans 4

2. What is the final answer?
Ans 10563(as far as I remember)

probability quesn on number of Junior and senior professors..
There are 6 senior and 4 junior profs outta which some 3 profs have to be selected for something.
Find the probability that atleast 1 Junior prof is selected.

A Prob of no Junior prof being selected=6C3/10C3=1/6

Hence prob of atleast one selection=1-(1/6)=5/6

Let p and q be positive nos.
On day one some person covered 1/p of the distance AB,2nd day 1/q of the remaining distamce,3rd day 1/p of the remaining distance and 4th day 1/q of the remaining distance.After 4th day,3/4th of the total distance was covered.

1.Find the value of p+q
Ans 7

2.Find the minimum distance covered on day one if the total distance was 100 Ans 25

i dont remember the ans for 3*4 matrix one....
i did it by (adding 1-15)-6-8

cause those were the no.s missing(6 and
since 3*4 matrix has 12 no.s ....
1 more no had to be eliminated from the given no.s....

hence (106-x) should be divisible by 12....
hence x is 10.....

a+b+c+d+e=10
a+b,b+c,c+d,d+e X is the maximum of dese.
Find the mininum value of X..my take would be ans is 4.ie when a=b=c=d=e=2.


find the max value of b/a.
1.a,a+b,a+2b are the three (sides or angles) of a triangle.
2.a and b are positive

i marked cannot be answered by using bo the statements together.

I agree with you, the answer is 4. The only problem was that among the options there were 2 options which included 4 i.e and . I think answer would be since the answer has to be greater than 4. Quant gods please confirm

one Q in quants which says the avg across the rows n columns of 3*4 matrix is the same
1. what is the no which vill not b used
2. wat is the avg?

I found sumthn like 40 or so and then looked at the choices and saw that they are too close! So dumped it!

actually i was getting 33.33 % approx so marked none of these
